Access mobile phone memory in a device independent way?

I have the requirement to access the following data, where available, on mobile phones with a device independent code

Needed data is

• Contacts
• Phone logs
• Appointments
• Tasks
• Voice notes and recor开发者_JAVA百科dings SMS messages
• Pictures Videos Application Data
• Email and Email attachments

This is needed to write a sort of cleanup application

Thanks!!!

I'm afraid it ain't as easy as that. You have to specify which phone models you are interested in. There is not "Device independent" way of doing this across brands. Sorry.
